You may remember getting toys for Christmas or your birthdays that your parents had to assemble. One such toy requires the use of 18 bolts. Since the manufacturer knows that he produces some defective bolts (about 6 % of his production), each package contains two extra bolts, i. e., 20. If this particular package contains one defective bolt, what is the chance that your parents will not encounter a defective bolt while assembling your toy?

0.2901

Explanation:

P(Defective Bolt) = 0.06

P(Non-Defective Bolt) = 0.94

n = 20

Let X be the random variable which indicates the number of defective bolts and this follows a Binomial Distribution

Therefore:

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
